What to do if my Zodiac Water Filtration Systems shows 'NO FLOW CHECK PUMP'?
- J
  Jasmine MartinezAug 17, 2025
  If your Zodiac Water Filtration System displays 'NO FLOW CHECK PUMP', it indicates a problem with water circulation. This can be due to a filter pump failure, dirty filter or skimmer(s), or closed by-pass valve(s). Inspect the pump, filter, skimmer(s), and by-pass valve(s), cleaning them as needed. Also, check the flow switch wire connections and ensure the flow switch is working correctly; replace it if necessary.

Why does my Zodiac Water Filtration Systems show a conductivity error?
- I
  irushAug 20, 2025
  A conductivity error in your Zodiac Water Filtration System could be due to several reasons. If your model has a temperature sensor, low water conductivity (low salt) might be the cause, so check the water temperature. It can also be caused by low salt levels due to water loss or dilution from filter backwash, water renewal, rain, or leaks. Measure the salt concentration using a salt tester or test strip, and add salt to maintain the level at 4 g/L or 2 g/L, depending on your model. Also, check the condition of the cell plates.

How to fix 'PROD. ERROR' on Zodiac Water Filtration Systems?
- M
  Michael SmithAug 22, 2025
  If your Zodiac Water Filtration System displays 'PROD. ERROR', it could stem from a few issues. First, check the power supply cord connections from the cell, both to the cell and inside the appliance, ensuring they are secure after switching off the appliance and the power supply to the control box. Another cause might be worn, scaled up, or broken cell plates, which would require cell replacement. It may also indicate an internal electronic problem in the control box, in which case you should check the power supply board.

What should I do if pH dosing STOP on my Zodiac Water Filtration Systems?
- N
  nielsenshannonAug 26, 2025
  If the pH dosing stops on your Zodiac Water Filtration System, it means that the pH value measured remains higher than the pH setpoint. To solve this problem you should check or replace the container, check and adjust the alkalinity (TA) of the pool water, and check/clean or replace the pH sensor.

What causes 'ORP PROD. STOP' in Zodiac Water Filtration Systems and how to resolve it?
- M
  Melinda SweeneyAug 28, 2025
  The 'ORP PROD. STOP' error in your Zodiac Water Filtration System indicates that the ORP setpoint hasn't been reached after prolonged chlorination. You should check the pool's chlorine level using a photometer or test strip, and inspect the ORP sensor wiring on both the control box and sensor holder. High cyanuric acid levels can also interfere with chlorine's effectiveness and ORP readings, so empty the pool using the bottom drain to reduce cyanuric acid concentration and perform shock chlorination with calcium hypochlorite to reduce chloramines. Also, check the condition of the cells and consider replacing the ORP sensor.

Why does my Zodiac Water Filtration Systems show 'pH REGUL. STOP'?
- T
  Terri GreenAug 31, 2025
  The 'pH REGUL. STOP' error on your Zodiac Water Filtration System means the pH setpoint hasn't been reached after 5 hours of injection. Start by checking the pool's pH with a photometer or test strip and inspect the pH sensor wiring on the control box and sensor holder. Ensure the pH minus container isn't empty and test the peristaltic pump. If the alkalinity is high, this can prevent pH reduction; consider reducing the alkalinity level. Replacing the pH sensor may also be necessary.

What to do if my Zodiac Water Filtration Systems is overheating?
- T
  Teresa MitchellSep 2, 2025
  If your Zodiac Water Filtration System is overheating, it means the temperature inside the control box is too high. To prevent this, protect the box from direct sunlight if it's installed outdoors. The chlorination process slows above 85°C and stops above 90°C to protect the electric circuits. Chlorination will resume automatically once the temperature decreases.

Why does my Zodiac Water Filtration Systems display 'LOW WATER TEMP.'?
- T
  Tina SaundersSep 5, 2025
  Your Zodiac Water Filtration System displays 'LOW WATER TEMP.' because the water temperature measured by the appliance's temperature sensor is 10°C or less. Production stops to protect the cell. Chlorination will automatically resume at the Low mode chlorination rate between 10 and 15°C, and at the normal chlorination rate when the temperature exceeds 15°C.

Why is there no visible chlorine production on the cell plates of my Zodiac Water Filtration Systems?
- J
  Jimmy OlsonSep 8, 2025
  If you observe no visible chlorine production on the cell plates of your Zodiac Water Filtration System, it may be because chlorination is in the reversal period, or chlorination is set to less than 100% and is stopped. In either case, wait and see; chlorination should resume within the next 10 minutes.

What causes a 'pH LOW' error on my Zodiac Water Filtration Systems?
- E
  estradachristianSep 12, 2025
  A 'pH LOW' error on your Zodiac Water Filtration System indicates that the pH is less than 5. Check the pH sensor wiring on the control box and the sensor holder. Also, a faulty connection, calibration error, pH sensor failure, or a dirty sensor could be the cause, so check the sensor's operation. Low alkalinity can also reduce pH, so check and adjust the alkalinity.
